Interestingly, I ran into code today that failed because of this behavior. The
code uses lists allocated within a struct, and allocates a list of size 0 in
case the list is unused by the struct.  The check for NULL return value for
out-of-memory was tripped by malloc(0), so the program spuriously exited.  I
had to add a check to say that I wanted to use malloc(0)'s results, and another
check when free'ing to avoid passing NULL.
